Does anyone have any clue how to duplicate the cheese sauce from Taco Bell?

I LOVE Taco Bell cheese sauce. Like if you order a nachos the cheese that is on that. It is creamy, thick, cheesey, and has a hint of indiscriminent spice at the end of each bite. I've seen Taco Bell "queso with salsa" cheese bowls but the cheese tastes fake and I HATE the salsa incorporated in the cheese. I love to make nachos but always crave the Taco Bell cheese sauce. Does anyone have any clue how they make it? And how they get that hint of heat at the end of each bite?
